Autophagy
|July 24, 2007
Summary
New research reveals that angiogenesis inhibitors, like kringle 5 (K5) and endostatin, can induce autophagy in endothelial cells. Enhancing this autophagic response may improve cancer therapy effectiveness.
Area of Science:
- Cell Biology
- Molecular Biology
- Oncology
Background:
- Angiogenesis is crucial for development and tissue function, but also drives cancer growth.
- Pathological angiogenesis is a target for cancer therapies.
- Kringle 5 (K5) and endostatin are known angiogenesis inhibitors.
Purpose of the Study:
- To investigate the effects of K5 and endostatin on endothelial cells.
- To explore the role of autophagy in angiogenesis inhibition.
- To identify novel therapeutic targets for enhancing anti-angiogenesis strategies.
Main Methods:
- Treatment of endothelial cells with K5 and endostatin.
- Analysis of apoptosis and autophagy pathways.
- Investigation of Beclin 1 and Bcl-2 complex alterations.
- Assessment of autophagy's role in response to anti-angiogenic treatment.
Main Results:
- K5 and endostatin induce both apoptosis and autophagy in endothelial cells.
- Both inhibitors upregulate Beclin 1, affecting the Beclin 1-Bcl-2 complex.
- Autophagy induction is independent of nutritional/hypoxic stress or VEGF.
- Knocking down Beclin 1 enhances apoptosis, increasing cell death.
Conclusions:
- Angiogenesis inhibitors can trigger autophagy in endothelial cells.
- The autophagic pathway is a novel target for improving anti-angiogenesis therapies.
- Modulating autophagy alongside traditional inhibition offers a promising therapeutic approach.

01:24Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
01:27Autophagy
Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

01:10Mechanism of Angiogenesis
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
01:18Autophagic Cell Death
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

01:36Delivery Pathways to the Lysosome
Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.
Endocytosis
In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...

03:03mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
